## Subject pose and expression

### Facial focus

The subject's face must be in sharp focus with the following characteristics:

* **Gaze:** Looking directly at the camera
* **Camera angle:** Slightly low angle so the subject appears to be looking down slightly, similar to their appearance on a video call
* **Facial expression:** Neutral expression required
  * No extreme expressions
  * Face should appear relaxed
  * Mouth should be closed but not held tightly
* **Pose reference:** Replicate the provided reference pose as closely as possible

## Framing and composition

### Centering

* **Horizontal:** Position the subject in the center of the frame
* **Vertical:** Position the subject's mouth-line at approximately 50% of the frame height

### Additional framing guidelines

* **Headroom:** Adequate vertical space above the subject's head, equivalent to roughly 25% of the total image height
* **View:** The subject's shoulders and chest must be clearly visible in the shot
* **Body orientation:** The subject should be facing the camera directly

## Environment and appearance

### Clothing

Avoid wearing clothing with large text or distracting logos.

### Background

Simple, uncluttered backgrounds are preferred.

### Camera distance

The ideal distance between the camera and the subject is approximately 2 meters, although this may vary depending on the camera lens used.
